About These Birds
Auckland Teal
A tiny flightless teal with dark brown plumage and a green speculum. Endemic to the Auckland Islands subantarctic group. Wings are reduced, making it completely flightless. Survives only on predator-free islands. Feeds mainly on invertebrates along freshwater streams.
Mandarinente
Die Mandarinente gilt weithin als die schönste Ente der Welt. In der ostasiatischen Kultur symbolisiert sie Liebe und Treue, da sie feste Paarbindungen eingeht. Anders als die meisten Enten nistet die Mandarinente in Baumhöhlen bis zu 9 Meter über dem Boden, sodass die erst einen Tag alten Küken zu Boden springen müssen.
